ABSTRACT:
An adjustable two-way valve device is described that is embodied as a rotary valve. According to the invention the use of the rotary valve as a two-way valve is achieved by the skillful arrangement of passage openings of a valve plate with respect to control openings of a valve element. Thus it is possible to control mass or mixed flows independently of or dependent on one another with only one valve element. In particular a use in the field of exhaust gas recirculation with a bypass line and an exhaust gas cooler is advantageous, since mixed flows and thus temperatures can be run.
